Silk'n Bella Glide hair removal system

the case has a water stain but don't let that dissuade you. I bought this from Costco a few years ago and literally used it a couple times. sadly, all my coarse hair I wanted gone is gray. it doesn't work on my gray hair. I kept it around a couple years in the vain hope Id revert back to dark hair. besides the water stain this is in practically new condition.
